Solar activity report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 278 Issued at 2200Z on 05 OCT 1997

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

SOLAR ACTIVITY HAS BEEN VERY LOW. REGION 8091 (N23E21) PRODUCED A B3.9/SF AT 05/1757Z. A SPACE-BORNE INSTRUMENT DETECTED A CORONAL MASS EJECTION IN THE SE QUADRANT OF THE SOLAR DISK NEAR REGION 8090 (S28E03) COINCIDENT WITH THE FLARE IN REGION 8091.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN VERY LOW FOR THE ENTIRE PERIOD.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES.
IIB. Geophysical Activity Forecast
GEOPHYSICAL FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR NEXT 12-18 HOURS BECOMING UNSETTLED-ACTIVE THEREAFTER DUE TO FAVORABLE POSITIONING OF AN EXTENSION OF THE NORTHERN POLAR CORONAL HOLE.
